Explanation:
A chemical synapse begins when an (3)<em>action potential reaches the axon terminal depolarizing the membrane</em> leading to the opening of the voltage-gated Na+ channels, this Na+ ions will then depolarize the presynaptic membrane, opening the voltage-gated Ca2+ channels. (2)<em>Calcium ions then will initiate a cascade entering the neuron </em>that will lead to the fusion of synaptic vesicles with the presynaptic membrane (5)<em>causing the releasing of neurotransmitters into the synaptic cleft.</em> (1)<em>These neurotransmitter will diffuse across the synaptic place in order to bind to the receptors on the postsynaptic membrane,</em> (4)<em>particulary into the ligand-gated channels, opening them.</em>

Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are
and
. They typically bond to themselves.
Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for
. We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.
Answer: As Earth orbits our Sun, the position of its axis relative to the Sun changes. This results in a change in the observed height of our Sun above the horizon. For any given location on Earth, our Sun is observed to trace a higher path above the horizon in the summer, and a lower path in the winter.
